Introduction
Introduction
The  D-Link  DI-624M  Super  G  Smart Antenna  Wireless  Router  is  an  802.11g  high-
performance, wireless router that supports high-speed wireless networking at home, 
at work or in public places.  
Unlike most routers, the DI-624M provides data transfers at up to 108 Mbps (compared 
to the standard 54 Mbps) when used with other D-Link Super G Smart Antenna products. 
The 802.11g standard is backwards compatible with 802.11b products. This means 
that you do not need to change your entire network to maintain connectivity. You may 
sacrifice some of 802.11g’s speed when you mix 802.11b and 802.11g devices, but you 
will not lose the ability to communicate when you incorporate the 802.11g standard into 
your 802.11b network. You may choose to slowly change your network by gradually 
replacing the 802.11b devices with 802.11g devices .
In addition to offering faster data transfer speeds when used with other 802.11g products, 
the DI-624M has the newest, strongest, most advanced security features available today.  
When used with other 802.11g WPA  (WiFi Protected Access) compatible products in 
a network, the security features include:
WPA:  Wi-Fi Protected Access authorizes and identifies users based on a secret 
key that changes automatically at a regular interval. WPA uses TKIP (Temporal Key 
Integrity Protocol) to change the temporal key every 10,000 packets (a packet is a 
kind of message transmitted over a network.) This insures much greater security than 
the standard WEP security. (By contrast, the older WEP encryption required the keys 
to be changed manually.)

Wireless Basics
Wireless Basics
D-Link wireless products are based on industry standards to provide easy-to-use and 
compatible  high-speed  wireless  connectivity  within  your  home,  business  or  public 
access wireless networks. D-Link wireless products will allow you access to the data 
you want,  when and where you want  it. You  will be  able to enjoy  the freedom  that 
wireless networking brings.
A WLAN is a cellular computer network that transmits and receives data with radio signals 
instead of wires. WLANs are used increasingly in both home and office environments, 
and public areas such as airports, coffee shops and universities. Innovative ways to 
utilize WLAN technology are helping people to work and communicate more efficiently. 
Increased mobility and the absence of cabling and other fixed infrastructure have proven 
to be beneficial for many users.
Wireless users can use the same applications they use on a wired network.  Wireless 
adapter cards used on laptop and desktop systems support the same protocols as 
Ethernet adapter cards. 
People use wireless LAN technology for many different purposes:
Mobility -  Productivity increases when people have  access to  data in any  location 
within the operating range of the WLAN.  Management decisions based on real-time 
information can significantly improve worker efficiency.
Low Implementation Costs – WLANs are easy to set up, manage, change and relocate. 
Networks that frequently  change can benefit  from  WLANs ease of  implementation. 
WLANs can operate in locations where installation of wiring may be impractical.
Installation and Network Expansion - Installing a WLAN system can be fast and easy 
and can eliminate the need to pull cable through walls and ceilings. Wireless technology 
allows the network to go where wires cannot go - even outside the home or office.
Scalability – WLANs can be configured in a variety of topologies to meet the needs 
of specific applications and installations. Configurations are easily changed and range 
from peer-to-peer networks suitable for a small number of users to larger infrastructure 
networks to accommodate hundreds or thousands of users, depending on the number 
of wireless devices deployed.
Inexpensive  Solution  -  Wireless  network  devices  are  as  competitively  priced  as 
conventional Ethernet network devices.

Wireless Basics
Installation Considerations 
The D-Link DI-624MSuper G Smart Antenna Wireless Router lets  you access your 
network, using a wireless connection, from virtually anywhere within its operating range. 
Keep in mind, however, that the number, thickness and location of walls, ceilings, or 
other objects that the wireless signals must pass through, may limit the range. Typical 
ranges vary depending on the types of materials and background RF (radio frequency) 
noise in your home or business. The key to maximizing wireless range is to follow these 
basic guidelines:
1  Keep the number of walls and ceilings between the DI-624M and other network 
devices  to a minimum - each wall or ceiling can reduce your D-Link wireless 
product’s range from 3-90 feet (1-30 meters.) Position your  devices so that the 
number of walls or ceilings is minimized.
2  Be aware of the direct line between network devices. A wall that is 1.5 feet thick 
(.5 meters), at a 45-degree angle appears to be almost 3 feet (1 meter) thick. 
At a 2-degree angle it looks over 42 feet (14 meters) thick! Position devices so 
that the signal will travel straight through a wall or ceiling (instead of at an angle) 
for better reception.
3  Building Materials can impede the wireless signal - a solid metal door or aluminum 
studs may have a negative effect on range. Try to position wireless devices and 
computers with wireless adapters so that the signal passes through drywall or 
open doorways and not other materials.
4  Keep your product away (at least 3-6 feet or 1-2 meters) from electrical   
devices or appliances that generate extreme RF noise.
Standards-Based Technology
The DI-624M Super G Smart Antenna Wireless Router utilizes the 802.11g standard.
The IEEE 802.11g standard is an extension of the 802.11b standard.  It increases the 
data rate up to 54Mbps within the 2.4GHz band, utilizing OFDM technology.
This means that in most environments, within the specified range of this device, you 
will be able to transfer large files quickly or even watch a movie in MPEG format over 
your network without noticeable delays. This technology works by transmitting high-
speed digital data over a radio wave utilizing OFDM (Orthogonal Frequency Division 
Multiplexing)  technology.  OFDM  works  by  splitting  the  radio  signal  into  multiple 
smaller sub-signals that are then transmitted simultaneously at different frequencies 
to  the  receiver.    OFDM  reduces  the  amount  of  crosstalk  (interference)  in  signal 
transmissions. 
The DI-624M is backwards compatible with 802.11b devices. This means that if you 
have an existing 802.11b network, the devices in that network will be compatible with

Some  applications  require  multiple  connections,  such  as  Internet  gaming,  video 
conferencing, Internet telephony and others. These applications have difficulties working 
through  NAT  (Network Address  Translation).  Special Applications  makes  some  of 
these applications work with the DI-624M. If you need to run applications that require 
multiple connections, specify the port normally associated with an application in the 
“Trigger Port” field, select the protocol type as TCP or UDP, then enter the public ports 
associated with the trigger port to open them for inbound traffic.
The DI-624M provides some predefined applications in the table on the bottom of the

1. The computer used to configure the DI-624M cannot access the Configuration 
menu.
n Check that the Ethernet LED on the DI-624M is ON. If the LED is not ON, check 
that the cable for the Ethernet connection is securely inserted.
n Check that the Ethernet Adapter is working properly.  Please see item 3  (Check 
that  the  drivers  for  the  network  adapters  are  installed  properly)  in  this 
Troubleshooting section to check that the drivers are loaded properly.
n Check that the IP Address is in the same range and subnet as the DI-624M. 
Please  see  Checking  the  IP  Address in Windows  XP  in  the  Networking 
Basics section of this manual.
Note:  The IP Address of the DI-624M is 192.168.0.1. All the computers on the network 
must have a unique IP Address in the same range, e.g., 192.168.0.x. Any computers 
that have identical IP Addresses will not be visible on the network. They must all have 
the same subnet mask, e.g., 255.255.255.0.
n Do a Ping test to make sure that the DI-624M is responding. Go to Start>Run>Type

Troubleshooting
4.  What variables may cause my wireless products to lose reception?
D-Link products let you access your network from virtually anywhere you want.  However, 
the positioning of the products within your environment will affect the wireless range.  
Please refer to Installation Considerations in the Wireless Basics section of this 
manual for further information about the most advantageous placement of your D-Link 
wireless products.
5.  Why does my wireless connection keep dropping?
n Antenna Orientation- Try different antenna orientations for the DI-624M. Try to 
keep the antenna at least 6 inches away from the wall or other objects.
n If  you  are  using  2.4GHz  cordless  phones,  X-10  equipment  or  other  home 
security systems, ceiling fans, and lights, your wireless connection will degrade 
dramatically or drop altogether.  Try changing the Channel on your Router, Access 
Point and Wireless adapter to a different Channel to avoid interference.
n Keep your product away (at least 3-6 feet) from electrical devices that generate 
RF noise, like microwaves, Monitors, electric motors, etc.
6.  Why can’t I get a wireless connection?
If you have enabled Encryption on the DI-624M, you must also enable encryption on 
all wireless clients in order to establish a wireless connection.
n For 802.11b, the Encryption settings are: 64, 128, or 256 bit.  Make sure that 
the encryption bit level is the same on the Router and the Wireless Client.
n Make sure that the SSID on the Router and the Wireless Client are exactly the 
same.  If they are not, wireless connection will not be established. 
n Move the DI-624M and the wireless client into the same room and then test the 
wireless connection. 
n Disable all security settings. (WEP, MAC Address Control)\
n Turn off your DI-624M and the client. Turn the DI-624M back on again, and then 
turn on the client. 
n Make sure that all devices are set to Infrastructure mode. 
n Check that the LED indicators are indicating normal activity. If not, check that 
the AC power and Ethernet cables are firmly connected.
n Check that the IP Address, subnet mask, gateway and DNS settings are correctly 
entered for the network. 
n If  you  are  using  2.4GHz  cordless  phones,  X-10  equipment  or  other  home 
security systems, ceiling fans, and lights, your wireless connection will degrade 
dramatically or drop altogether. Try changing the Channel on your DI-624M, and 
on all the devices in your network to avoid interference.
n Keep your product away (at least 3-6 feet) from electrical devices that generate 
RF noise, like microwaves, Monitors, electric motors, etc.

Frequently Asked Questions
1  Why can´t I access the Web based configuration?
When entering the IP Address of the DI-624M  (192.168.0.1), you are not connecting 
to the Internet or have to be connected to the Internet. The device has the utility built-
in to a ROM chip in the device itself. Your computer must be on the same IP subnet to 
connect to the web-based utility.
To  resolve  difficulties  accessing  a    Web  utility,  please  follow  the  steps  below.  
Step 1: Verify physical connectivity by checking for solid link lights on the device. If you 
do not get a solid link light, try using a different cable or connect to a different port on 
the device if possible. If the computer is turned off, the link light may not be on.
What type of cable should I be using?
The following connections require a Crossover Cable: 
Computer to Computer 
Computer to Uplink Port 
Computer to Access Point 
Computer to Print Server 
Computer/XBOX/PS2 to DWL-810 
Computer/XBOX/PS2 to DWL-900AP+ 
Uplink Port to Uplink Port (hub/switch) 
Normal Port to Normal Port (hub/switch) 
The following connections require a Straight-through Cable: 
Computer to Residential Gateway/Router 
Computer to Normal Port (hub/switch) 
Access Point to Normal Port (hub/switch) 
Print Server to Normal Port (hub/switch) 
Uplink Port to Normal Port (hub/switch) 
Rule of Thumb: 
”If there is a link light, the cable is right.”

Frequently Asked Questions
What´s  the  difference  between  a  crossover  cable  and  a  straight-through  cable?  
The wiring in  crossover and straight-through  cables are different. The two  types  of 
cable  have  different  purposes  for  different  LAN  configurations.  EIA/TIA  568A/568B 
define the wiring standards and allow for two different wiring color codes as illustrated 
in the following diagram.
*The wires with colored backgrounds may have white stripes and may be denoted that 
way in diagrams found elsewhere.
How to tell straight-through cable from a crossover cable:
The main way to tell the difference between the two cable types is to compare the wiring 
order on the ends of the cable. If the wiring is the same on both sides, it is straight-
through cable. If one side has opposite wiring, it is a crossover cable.
All you need to remember to properly configure the cables is the pinout order of the 
two cable ends and the following rules:
A  straight-through  cable  has  identical  ends.  A  crossover  cable  has  different 
ends.
It makes no functional difference which standard you follow for straight-through cable 
ends, as long as both ends are the same. You can start a crossover cable with either 
standard as long as the other end is the other standard. It makes no functional difference 
which end is which. The order in which you pin the cable is important. Using a pattern 
other than what is specified in the above diagram could cause connection problems.
When  to  use  a  crossover  cable  and  when  to  use  a  straight-through  cable: 
Computer to Computer – Crossover
Computer to an normal port on a Hub/Switch – Straight-through
Computer to an uplink port on a Hub/Switch - Crossover
Hub/Switch uplink port to another Hub/Switch uplink port – Crossover
Hub/Switch uplink port to another Hub/Switch normal port - Straight-through

4 Can I use my D-Link Broadband Router to share my 
Internet connection provided by AOL DSL Plus?
In most cases yes. AOL DSL+ may use PPPoE for authentication bypassing the client 
software. If this is the case, then our routers will work with this service. Please contact 
AOL if you are not sure.
To set up your router:
Step 1: Log into the web-based configuration (192.168.0.1) and configure the WAN 
side to use PPPoE. 
Step 2: Enter your screen name followed by @aol.com for the user name. Enter your 
AOL password in the password box. 
Step 3: You will have to set the MTU to 1400. AOL DSL does not allow for anything 
higher than 1400.
Step 4: Apply settings. 
Step 5: Recycle the power to the modem for 1 minute and then recycle power to the 
router. Allow 1 to 2 minutes to connect. 
If you connect to the Internet with a different internet service provider and want to use 
the AOL software, you can do that without configuring the router’s firewall settings. You 
need to configure the AOL software to connect using TCP/IP. 
Go  to  http://www.aol.com  for  more  specific  configuration  information  of  their 
software.
5 How do I open ports on my router?
To allow traffic from the internet to enter your local network, you will need to open up 
ports or the router will block the request. 
Step  1:  Open  your  web  browser  and  enter  the  IP Address  of  your  D-Link  router 
(192.168.0.1). Enter username (admin) and your password (blank by default). 
Step  2:  Click  on  Advanced  on  top  and  then  click  Virtual  Server  on  the left  side.

Step 3: Check Enabled to activate entry. 
Step 4: Enter a name for your virtual server entry. 
Step 5: Next to Private IP, enter the IP Address of the computer on your local network 
that you want to allow the incoming service to. 
Step 6: Choose Protocol Type - either TCP, UDP, or both. If you are not sure, select 
both. 
Step 7: Enter the port information next to Private Port and Public Port. The private 
and public ports are usually the same. The public port is the port seen from the WAN 
side, and the private port is the port being used by the application on the computer 
within your local network. 
Step 8: Enter the Schedule information. 
Step 9: Click Apply and then click Continue. 
Note: Make  sure DMZ  host is  disabled. If DMZ is enabled, it will disable all Virtual 
Server entries. 
Because our routers use NAT (Network Address Translation), you can only open a 
specific port to one computer at a time. For example: If you have 2 web servers on 
your network, you cannot open port 80 to both computers. You will need to configure 1 
of the web servers to use port 81. Now you can open port 80 to the first computer and 
then open port 81 to the other computer.

6 What is DMZ?
Demilitarized Zone:
In computer networks, a DMZ (demilitarized zone) is a computer host or small network 
inserted  as  a  neutral  zone  between  a  company´s  private  network  and  the  outside 
public network. It prevents outside users from getting direct access to a server that 
has company data. (The term comes from the geographic buffer zone that was set 
up between North Korea and South Korea following the UN police action in the early 
1950s.) A DMZ is an optional and more secure approach to a firewall and effectively 
acts as a proxy server as well.
In a typical DMZ configuration for a small company, a separate computer (or host in 
network terms) receives requests from users within the private network for access to 
Web sites or other companies accessible on the public network. The DMZ host then 
initiates sessions for these requests on the public network. However, the DMZ host is 
not able to initiate a session back into the private network. It can only forward packets 
that have already been requested.
Users of the public network outside the company can access only the DMZ host. The 
DMZ may typically also have the company´s Web pages so these could be served to 
the outside world. However, the DMZ provides access to no other company data. In the 
event that an outside user penetrated the DMZ hosts security, the Web pages might 
be corrupted but no other company information would be exposed. D-Link, a leading 
maker of routers, is one company that sells products designed for setting up a DMZ
7 How do I configure the DMZ Host?
The DMZ feature allows  you  to forward all incoming  ports  to one computer on  the 
local network. The DMZ, or Demilitarized Zone, will allow the specified computer to be 
exposed to the Internet. DMZ is useful when a certain application or game does not 
work through the firewall. The computer that is configured for DMZ will be completely 
vulnerable on the Internet, so it is suggested that you try opening ports from the Virtual 
Server or Firewall settings before using DMZ. 
Step 1: Find the IP address of the computer you want to use as the DMZ host.
To find out how to locate the IP Address of the computer in Windows XP/2000/ME/9x or 
Macintosh operating systems please refer to Step 4 of the first question in this section 
(Frequently Asked Questions).

Step 3: Click the Advanced tab and then click on the DMZ button. Select Enable and 
type in the IP Address you found in step 1. 
Step 4: Click Apply and then Continue to save the changes. 
Note: When DMZ is enabled, Virtual Server settings will still be effective. Remember, 
you cannot forward the same port to multiple IP Addresses, so the Virtual Server settings 
will take priority over DMZ settings.
